Rapid prototyping technology has significant benefits in the medical field, allowing for the precision manufacturing of surgical instruments, implants, and anatomical models. Various technologies like stereolithography, selective laser sintering, fused deposition modeling, and polyjet 3D printing are used to create customized medical devices and models from patient scans in materials like polyurethane resin, PEEK, ABS, polyamide and cobalt chrome. These prototypes aid in surgery planning and device design for applications such as orthopedics, dental work, cardiovascular procedures and more.

in medical field

2. Continuous technological advancements in Rapid Prototyping technology ensure
success for all industries that require extreme precision and customization. In
particular, this technology has had significant results in the medical field, not only
for the realization of machines and surgical instruments, but also for the
manufacturing of orthopedic and dental implants, for the three-dimensional
reconstruction of skeletal structures or anatomical parts.

3. Medical equipment
Case for multi-use device
Material: Polyurethane resin
Technology: Vacuum Casting
The stereolithography technology is used to produce masters in silicone, as molds
for the realization of medical devices. The polyurethane resin is poured in the
molds, in order to obtain the final model. A subsequent finish with the metallization
can be applied to the device to realize aesthetic products.

4. Medical equipment
Medical pump
Material: PEEK
Technology: Selective Laser Sintering
(SLS)
SLS technology allow to reproduce 3D
printed models with high complexity.
Moreover, with this technology, it is
possible to use a material, like PEEK,
biocompatible, resistant to high
temperature and with high mechanical
properties.

5. Medical equipment
Breathing mask
Material: Polyurethane resin
Technology: Vacuum Casting
Silicone masters manufactured with
the stereolithography tecnology are
used as molds for the realization of
medical equipment.
The polyurethane resin, with a
hardness from 30 to 95 ShA, is poured
in the molds, in order to obtain the final
model.

6. Skeletal structures
Hand model
Materials: Trasparent rubber and rigid
material Simil ABS
Technology: Objet Polyjet
The 3D Objet Polyjet printing allows to
create plastic and rubber models with
different hardness, co-molded in a
single printing. All skeletal structures of
the human body can be manufactured,
starting from digital diagnostic images.

7. Skeletal structures
Femur model
Material: ABS
Technology: Fused Deposition
Modeling (FDM)
FDM and Sintering technologies allow
to create bone models, in 1:1 scale.
These can be useful for orthopaedic
clinicians to better study the bone
fractures and plan the surgery.

8. Skull model
Material: Polyamide
Technology: Selective Laser Sintering
(SLS)
3D printing technologies allow to
realize anatomic models of skulls,
which are used for:
• Maxillo-facial surgery;
• Plastic surgery;
• Trauma care.

9. Knee implant
Material: Cobalt Chrome super-alloy
Technology: Direct Metal Laser
Sintering (DMLS)
DMLS technology allows to
manufacture orthopaedic implants with
biocompatible materials, such as
Stainless Steel, Titanium and Cobalt
chrome alloys. Moreover, the capability
to produce customized devices with a
superficial structure which facilitates
the surrounding bone ingrowth is
important for a perfect integration of
implant with the patient natural bone.

10. Odontoiatric implants
Odontoiatric model
Material: Vero White (high temperature)
Technology: Objet Polyjet
Dental laboratories around the world use
Rapid Prototyping, in particular the
Polyjet Objet 3D printer, to create highly
accurate models directly from digital files
acquired by means of oral examination.
The resulting 3D print prototype faithfully
reproduces the anatomy of the patient
allowing the clinician to quickly ascertain
the best information about the clinical
case, in turn facilitating the best plan of
action or any other type of application.

11. Heart model
Material: Tango Plus (Rubber)
Technology: Objet Polyjet
Scans derived from digital diagnostics
are processed to obtain .stl files of 3D
heart models. These files are input into
the 3D printer, for the realization of the
3D prototype. This prototype
reproduces faithfully the anatomy of
the organ. In this way, surgeons can
quickly acquire the desired information
on the clinical case, they can plan the
cardiovascular surgery and design
patient-specific implants.
Cardiovascular structures

12. Vascular and valves models
Material: Tango Plus (Rubber)
Technology: Objet Polyjet
Prototypes of cardiac valves can be
realized to conduct experimental tests or
to design implantable patient-specific
valves. In addition, vascular models,
derived from CT images of a subject, can
be used for the hemodynamic analysis for
different vascular pathologies.
